IMPROVEMENT IN- HORSE-POWER APPARATUS.

Th Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it known that I, ABRAHAM Gra-An', of Richmond, in the county of' Wayne'and State of Indiana,

have invented certain Improvements in Mounted Horse-Powers `and'I do hereby declare that the following is a full, clear, and exact description thereof, reference heilig had to the annexed drawing making part of this'specification, in which- Figure 1 is a plan or top view of' this horsepoweras it appears when mounted upon wheels, and staked or fastened in position for use, the arrangement of gearing being also shown.

Figure 2 is'a bottom view of the same, with the `wheels and fastening devices removed.

Figure 3 isa longitudinal vertical section on line :t x, of' fig. l.

Figure 4 isa cross-section of the bridge-piece, showing the slot in which the pin which holds the masterwheel works.

Corresponding letters refer to corresponding parts in the several figures.

This'illlvention relates to that class of' horse-powers which is mounted upon wheels, for convenience in transportation, and it consists in the construction,'com hination, and arrangement of certain parts thereof, as will be more fully explained hereinafter.

` A inthe drawing refers to thc main frame of the machine, which may be constructed in any well known yf'onn, so as to consist of two pieces of timber arranged parallel to each other, but zit-,proper distances apart, to receive and support the gearing of the-machine.

Al Al refer to metal cross-beams, the ends of' which re provided with flanges by which to attach them to Vthe side rails of' the frame.

These beams are furnished with apertures, to which the boxes which support the shaft which transfers the motion to the machine to be driven are attached, they being found to be of great advantage, Ain that they keep thc shaft always in line, the boxes not being liable to become loosened, asis the case when they are fastened to wooden beams. The rear one of these cross-beams is provided with a socket upon its upper edge aud at one of its ends, to receive the end of a brace, which 'is used to hold the machine in position when in use, a similar socket being bolted to the' frame-work at the frontend, for the same purpose. The apertures in thef'orward metal cross-beams are so arranged as to permit the diagonal brace, a, which is usedto hold the frame together, to pass through them. Other cross-beams of' wood are provided, one at. the forward end of the frame, and others at such points as they are needed to support the various parts of the machine.

A2 refers to the axles; and

B refers to what is usuallytermed the master-wheel of the machine, ithaving, at its center, a metal hub,

which is provided with pockets for the arms, whichl connect it with the rim of said wheel, and also for the reception of the arms or sweeps to which the horses are attached, The rim of' this wheel is of' metal, and has, upon its inner periphery, cogs, inthe usual manner, so that, as it is pnt in motion, such motion is communicated to the. pinions Bl B, and bevel-wheels B2 B2; the latter mesh intoI and turn the pinio'ns Ba .Bi upon the shaft B, which, by means of' couplings upon its ends, communicates motion to any machine to which it is connected'.

C refersto a bar of" metal, termed the bridge-piece, it being so constructed as to receive, in openings formed in its outer end, the pins or spindles upon which the gear-wheels Bl and l5 revolve, it.being secured to the cross-bars or beams of frame A'jnst inside of' such points, and also at its center, where it ,receives and holds the pin or spindle upon which the master-wheel turns, its under surfacebcing provided with projections, to receivel and hold. the inner endof tenons. as shown in fig. 1.

The peculiar-ity of the construction of 'this bridge consists in the fact that it has formed, inits center, an aperture of suficient size to admit into rit a peculiarly f'ormed head or box, which is upon the bolt or spindle C2, soon to be described.

` Tothe under side of' this bridge-piece there are bolted two jaws, Cl O, the inner ends of which are turned upwaxl ator nearly at right angles to their Vlower surfaces, so that they may enter the apertnrein the bridge-piece, and .partially'closo up the same, as

shown vin fig. 2 ofthe drawing.

'.lhe bridge-piece is further secured by metallic braces, c c, attached to ears on the same, near each end, and thence passing in opposite direction to the side beams of' the frame, through which they extend sufficiently far to receive tightening-nuts.

(Prefers tothe pin or spindle upon which the lnasv 4ter-wheel B revolves, its upper portion being turned to fit al hole bored in `the hub 'of such wheel, while its lower end is provided witha box or projection, into two sides .of which recesses are formed for the reception of Ithe ends of' the jaws Cl C, as above stated.

vThis box or"head of the pin, and the jaws C1 C nearly fill the aperture in the bridge-piece longitudinally, thus holding said piu or spindle iu its place, while transversely its head, ol' the box attached thereto, has suicient room to move fora considerable distance, the objeetbeing to form', at this point, au adg v justable bearing for the master-wheel, iuorder that, in the event of any small obstructions being in the teeth of thc master-wheel or pinions which it drives, it may move slightly in any direction, and thus, by adjusting itself', prevent the breaking of the gearing.

C CS refer to the pinsor spindles upon which the pinions B1, and bevel-wheels B2 revolve, they being of tile-form shown in iig. 3, where lit will be seen that their lower ends rest in sockets formed in pedestals secured to the cross-beams of frame A, their lower ends being reduced in diameter for that purpose.

That portion ot this pin yor spindles which passes through the bevel-wheel B2 is ot greater' diameter than any other portion ot it, while that part which 'passes through the pinion Bl is of less. r;[he arrangement of .this pin or spindle with reference to the wheels through which it passes, and the parts which support its ends, is such that it can turn freely within such supports, while the wheels can freely turn upon such pin or spindle, the object being to prevent said pin or spindle from wearing ilatnponv any portion ot' its surface, as is done when'it is held fast in one position, and also to facilitate the repairing of the machine at that point when it becomes necessary.

D D refer to stakes or frames, which are attached to the frame of the machine. by means o f' stake-irons, so that, when it becomes desirable to remove the machine, the sweeps or arms and the coupling-shaft may be placed thereon, and be carried withthe other parts.

The above-described parts, with theexception of the metal bars or beams A1, the adjustable piu or spindle Cz, and the loose pins or spindles C3, when seperately considered, form no part of my present invention, and consequently need not be more partic-` ularl y described here, while those hereinafter described separately, and as combined and arranged, form parts of myinvention. l

E E ret'er to braces, the' outer ends of which rest against stakes driven into the earth, the inner endsresting in the sockets E E1, atv the ends of the frame, as shown in iig. l. The oftice of these braces is to aid in holding the power firmly in position, they receiving a portion of the side strain or thrust, consequent upon the movements ot' the horses around the machine.

F F ret'cr to rods or bals of iron, which have aloop or ring formed in their outer ends for the reception of stakes, which are driven through them into the ground.. About midway of their length these rods are provided with a swivel-nut, F1, so arranged that, by turning the same, the length of the rods may be lengthened or shortened at pleasure, which arrangement, together with the manner ot'conuecting said rods to the shoe orA clamp, which is placed upon the wheel, is clearly shown in tig. 1 of the drawing.

F2 F2 refer to rods, which extend across the machine, and from the point where they connect with the rods l" F through the wheels, and to a suitable distance outside the opposite wheel, to receive a brake-block or shoe, and aunt, F5, t'or holding and tightening the arts. p F F refer to blocks of wood, which are placed upon the outside of the wheels, the rods Fz passing through or braces -F F are staked to the ground, are upon opposite. sides of the machine to those where the braces E E are staked, the objectfbeing to provide'two points of resist-ance to the side strain upon the machine, caused by the pull of the horses when passing the ends Y ot' the machine.

As au additional security against the side movement of the machine, pieces of planks, of any suit-able length, width, and thickness, are placed against the wheels which are nearest the braces F F, and a stake is d riven into the earth outside of said plank, so that, as the nuts in said rods are tightened-up, the machine will not be moved in thatdirection.v

The advantage derived from attaching the holding braces to the wheels over those attached to the frame ot' the machine, is that a much larger leverage is obtained, and, consequently, that the machine is held more iirmly in its position.

What I claiin-as myinvention, and desire to secure by Letters Patent, is-

1 Thel metal cross-beams Ain a horsefpower, when ymounted and operated as setforth.

2. The diagonal iron bracerod (t, in a horse-power frame, when mounted and operated on four wheels. as set forth. v

3. The clamp, shoe, and rod, for clamping and holding the wheels of a mounted power when in operation, as describedl 4. The combination and arrangement of the rods F and F, the shoes F, clamps F, and nuts F5, or their equivalents, -when used in connection with the mounted horse-power, substantially as and for thepurpose set forth.

5. The diagonal iron brace-rod (t, when used in combination with the two rods c c, attached to each end of the bridge-piece, and passing through each side ot' the frame, w'hen mounted. and operated as herein specified.

6. The master-pinions and. bevel-wheels, in combination with the loose stud-pins, when mounted and operated as herein set forth.

In testimony whereof` I have signed my name to this specification in the presence ot' two subscribing witnesses.
